MARINE-BOILER FURNACE.

SBEGIFICATION forming part of Letters Patent No. 670,719, dated March26. 1901.

Application filed December 29, 1900. Serial No. 41,502. (No model.)

To all whmn it may concern:

Be it known that I, JOHN ODEN MORRIS, a citizen of the United States,residing at Richmond, in the county of Henrico and State of Virginia,have invented new and useful Improvements in MarineBoiler Furnaces, ofwhich the following is a specification.

This invention relates to certain new and useful improvements inmarine-boiler fur- 1o naces, and is particularly adapted for use inconnection with marine engines.

The invention aims to construct a marineboiler furnace for consuming allthe combustibles contained in the fuel, thereby increasing thetemperature of the heat, obtaining a considerable saving in theconsumption of fuel, and deflecting the heat uniformly through theboiler-fines; and to this end the invention consists in providing thefire-box with a deflectingovall near the bridge-wall of the furnace andthe chamber for the products of combustion at the rear of thebridge-wall with a deflecting-wal1 for causing the prodnets ofcombustion to pass uniformly into the flues, thereby increasing therapid generation of steam.

The invention further aims to construct a marine-boiler furnace whichshall be extremely simple in construction, strong, du-

rable, efficient in its use, and comparatively inexpensive to set up.

The invention finally consists in the novel combination andarrangelnentof parts hereinafter more specifically described,illustrated in the accompanying drawings, and particularly point-ed outin the claims hereunto appended, and in describing the invention indetail reference is bad to the accompanying drawings, forming a part ofthis specification,

wherein like numerals of reference indicate corresponding partsthroughout both views, and in which- Figure 1 is a sectional elevationof my improved boiler-furnace. Fig. 2 is a detail view 5 of one of thebricks forming the deflectingwall and the tie for securing the same inposition.

Referring to the drawings by reference-numerals, 1 indicates the wallsof the boilerfurnace, 2 the fines, 3 the flue-sheet, 4 the top wall ofthe firebox 5, 6 the walls of the chamber 7, 8 the hollow bridge-wall,and 10 the grate-bars, the foregoing being the ordinary construction ofa marine-boiler furnace.

Secured to the top wall 4 of the flre-box,near the inner end thereof anda portion thereof above the bridge-wall, is a downwardly-extendinginclined deflector consisting of a series of bricks 11, constructed offireproof material and each formed with a countersunk opening 12,through which extend the hang ers or ties 13, provided on-their lowerends with the nut l4.-and near their upper ends with the screw-threadedportion 15, terminating at its lower end in the swell 0r offset 16. Thehanger or tie is screwed up into the top wall 4 of the fire-box untilthe latter is engaged by the swell or offset, forming a tight joint. Thehangers or ties gradually increase in length toward the rear of thefire-box, so that the deflector when in position will extend down wardlyat an inclination toward the rear of the fire-box and contract theopening between the chamber 7 and the fire-box 5, and, furthermore, thedeflector will cause the prodnets of combustion to be deflecteddownwardly at an inclination against the deflecting-wall of the chamber7. t

The deflecting-wall of the chamber 7 consists of an inclined lowersection 17, a vertical central section 18, and a curvilinear uppersection 19, each of which is formed of a series of bricks of fireproofmaterial similar to and secured in a like manner as the bricks employedin the deflector, the same referencenumerals being applied thereto.

By the employment of the inclined deflector near the end of the fire-boxthe passage of the products of combustion is retarded somewhat and thesmoke or other gases consumed 0 to a certain extent, increasing therebythe temperature of the heat and a saving in the consumption of fuel. Theproducts of combustion when leaving the fire-box will be deflectedagainst the vertical section 18 of the wall in the chamber-7 and thenpass upwardly and are deflected by means of the curvilinear uppersection 19 through the dues. The defleeting-wall causes the products ofcombustion to pass substantially uniformly through the fines, so that arapid generation of steam will take place. 1

The many advantages in constructing a marine-boiler furnace in themanner set forth by the foregoing description, taken in connection withthe accompanying drawings, will be apparent and it will be noted thatvarious changes can be made in the details of construction withoutdeparting from the general spirit of myinvention, which consists inproviding the deflector in the fire-box for retarding the passage of theproducts of combustion, and, further, providing a deflecting-wall forcausing the heating of the flues by the products of combustion in auniform manner.

Having thus fully described myinvention, what I claim as new, and desireto secure by Letters Patent, is-

1. In a marine-boiler furnace, the combination with the fire-box andboiler thereof, of a downwardly -inclined deflector arranged thereon,and a deflecting-wall consisting of inclined vertical and curvilinearsections arranged at the rear of the firebox and adapted to deflect theproducts of combustion through the flues of the boiler.

2. In a marine-boiler furnace, the combination With the fire-box andboiler thereof, of adownwardly-inclined deflector formed of a series offireproof bricks arranged in said firebox and adapted to retard thepassage of the products of combustion over the bridge-wall, and adeflecting-wall formed of a series of fireproof bricks arranged at therear of said fire-box and adapted to deflect the products of combustionthrough the flues of the boiler.

3. In a marine-boiler furnace, the combination with the fire-box andboiler thereof, of a series of fireproof bricks suspended therein andforming a downwardly extending inclined deflector for retarding thepassage of the products of combustion, a deflecting-wall formed ofinclined, vertical and curvilinear sections arranged at the rear of saidfire-box and adapted to deflect the products of combustion through theflues of the boiler, and means for tying said sections in position.

4. In a marine-boiler furnace, the combination With the fire-boxthereof, of a series of fireproof bricks suspended therein and forming adownwardly-extending inclined deflector for retarding the passage of theproducts of combustion, a deflecting-wall consisting of inclined,vertical and curvilinear sections each formed from a series of separatefireproof bricks, and means for tying said bricks in position.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JOHN ODEN MORRIS.
